Al/Cu bimetallic lug 25-150 mm² / 25-95 mm² SLIW57

Two-sided terminals for aluminum-copper connections

The SLIW57 terminal is a reliable solution for connecting aluminum and copper wires in electrical installations. Designed for wires with a cross-section of 25-150 mm² (main) and 25-95 mm² (branch), it provides a safe and durable connection, minimizing the risk of failure. The terminal's construction based on Insulation Piercing Connector (IPC) technology simplifies installation, eliminating the need to remove insulation from the wires.

Construction and application

The SLIW57 terminal is characterized by a solid construction using high-quality materials. The body is made of a composite material resistant to weather conditions and UV radiation, guaranteeing long-term operation even in harsh outdoor conditions. Current-carrying parts are tinned to ensure corrosion resistance and optimal conductivity. Steel elements – screws and washers – are made of stainless steel, which further increases the durability and reliability of the connection.

This terminal is used in low-voltage overhead lines, cable connections and wherever a reliable connection between aluminum and copper wires is required. The waterproof design makes it ideal for outdoor applications exposed to moisture and precipitation. The breakable head of the nut makes it easy to check the correctness of the connection and ensures tight fastening of the terminal.

Key features and benefits

• Versatility: The ability to connect aluminum and copper wires in one terminal eliminates the need to use different types of connectors.
• Waterproof: Ensures a reliable connection even in humid conditions, protecting against corrosion and failures.
• Easy installation: Insulation Piercing Connector (IPC) technology simplifies the installation process, saving time and reducing the risk of errors.
• Durability: The use of high-quality materials – tinned aluminum, stainless steel and composite materials – guarantees long-term operation of the terminal.
• Safety: A secure connection thanks to the construction with a breakable nut head and solid workmanship ensures the safety of the electrical installation.
• Application for various cross-sections: A wide range of permissible wire cross-sections (25-150 mm² for the main and 25-95 mm² for the branch) increases the flexibility of the terminal's application.
• Through channels: Both for the main and branch wires, the channels are through, which facilitates installation in tight spaces or when it is necessary to route cables further after connection.
